📄 PDF Generator

A lightweight Python project to generate optimized PDFs from image archives.
It extracts .jpg files from a .7z archive, resizes them to fit an A4 page, and combines them into a single PDF.

---

🚀 Features

• Extract .jpg images from .7z archives
• Resize/compress images for smaller PDF size
• Generate full-page PDFs with fpdf2
• Logging with loguru
• Modern dependency & linting setup with uv

---

📦 Installation

This project uses uv (a fast Python package/dependency manager).
Make sure you have it installed:

pip install uv

Then, install dependencies:

uv sync

This will create and manage a .venv automatically.

▶️ Usage

Run the PDF generator:

uv run main.py

(or whatever entrypoint you use — adjust the path accordingly).

The script will:

1. Extract images from input.7z into the ./images folder
2. Resize them to fit an A4 page (at ~150 DPI)
3. Generate output.pdf in the project root

🛠 Development

Run linting and auto-fixes with ruff:

uv run ruff check --fix

Format code:

uv run ruff format
